Specification of Letters Patent.

Application filed June 20, 19-13. Serial No. 774,742.

To all whom it may concern:

Be it known that we, ARTHUR GEORGE Booznn, J r., and Gnoncn HILL,citizens of the United States, residing, respectively, at Greenville,county of Greenville, and Tucapa-u, county of Spartanburg, in the Stateof South Carolina, have invented certain new and useful Improvements inDofiing-Machines, of which the following is a specification.

This invention relates to dofling machines arranged to travel along thesides of spinning frames for removing full bobbins from the spindles andreplacing empty bobbins thereon.

The machine herein disclosed is similar to that shown in our priorapplications Serlal Nos. 401,308, fil-edi November 8, 1907, 483,821,filed March 16, 1909, 485,001, filed March 22, 1909 and 621,317, filecl-April 15, 1911.

One of the objects of the present invention is to provide an improvedmechanism for actuating and controlling the machine.

Another object is to provide an improved 26 magazine for empty bobbinsand means for controlling the passage of the bobbins from said magazineonto the empty spindles.

The invention also relates to other 1m provements and advantages to bemore fully described hereinafter. In the accompanying drawings, Figures1 and 2' together constitute a front elevation of a dofling machineembodying our invention, the view also showing portions of a spinningframe with which the dofiing ma chine is associated. Figs. 3 and 4 takentogether constitute a sideelevation of the dolling machine and! afragmentary new of the spinning frame. Figs. 5 and 6 are sectionaldetail views taken on lines 5 5- and 6 6, respectively, of Fig. 2. F g.7 1s a fragmentary front elevational view and Fig. a front-to-rearsectional view, with parts omltted, illustrating certain mechanism atthe central portion of the machine. Fig. 9 1s a horizontal section online 9 9 of Figs. 2 and 7, showing the contour of a cam comprised in theactuatin means. Fig. 10' is a horizontal section in 't e plane of line10 10 of F ig. 7. Figs. 11 and 12 are horizontal sectional viewsillustrating, in two'difi'erent positions, a means for automaticallydisconnecting the driving motor from the operating mechanism. Figs. 13and 14 are diagrammatic views illustrating the development of a camwhich advances the dofiing machine step by step along the spinningframe. Figs. 15 and lfi'illustrate, in two different positions, a meansfor controlling the descent of the empty bobbins in the donning tube.Fig. 17 is an end elevation of the empty bobbin magazine and thesupporting means therefor. Figs. 18 and 19 are fragmental plan views ofthe bobbin magazine and the means for controlling the discharge ofbobbins therefrom.

The preferred embodiment of our invention which we have hereinillustrated comprises a suitable framework consisting of two sides 20, abase 21 connecting the lower ends of said sides, and a table 22 mountedupon and connecting the upper ends of said sides. The machine issupported upon a guide rail 23 011 the spinning frame A, by means of apair of grooved rollers 24 mount ed eccentrically in bearing brackets 25secured to the sides 20.

A link 26 connects arms 27 which are rigid with the bearings for therollers, and said bearings are arranged to be rotated by means of ahandle 28 (Fig. 2) to raise and lower the rollers with relation to thedoffer frame.

A pair of rollers 29 and 30 are mounted respectively in brackets 31 and32 on the sides 20, said latter rollers being arranged to bear againstthe lower flange of the spindle rail of the spinning frame, the weightof the dofler maintaining the rollers incontact with said spindle rail.

The dofl'er head 35 herein shown (see Fig. l) for grasping the fullbobbins and removing them from the spindles is substantially the sameconstruction as that illustrated in our application Serial No. 621,317above mentioned. Said head consists'of a plurality of inter-meshingspring-pressed fingers 36 extending in opposite directions from thecenter of the head to form two opposed grip ping jaws. These jaws arealternately opened and closed by means fully described in saidapplication. The dofl'er head is fixed upon the upper end of a bar 37which is slidably mounted in a bearing carried by the table 22 and in abearing 38 carried at the upper end of a guide member 39 fixed in thefrauneworlc (see Fig. 2). The lower end of the dofi'er bar 37 isrotatably mounted in a slide 40 which is grooved to engage with theedges of the guide member 39,

' cal reciprocating movement.

whereby the dofier head is guided for verti- Said head is reciprocatedby means of a lever 41 pivoted at 42 in the bracket 31 and connected atits free end by means of a link-43 to the slide 40.

The lever 41 is oscillated to reciprocate the dofi'er head by means tobe now described.

An electric motor is mounted on the base 21 and has a pinion 51 on itsarmature shaft which mesheswith a gear 52 fixed on a stub shaft which ismounted in a bearing bracket 53 carried by one of the sides 20.(SeeTigs. 2 and 6.) A pinion 54, also fixed on the latter shaft, mesheswith a spur gear 55 which is, fixed on a horizontal shaft 56 alsomounted in the bracket 53. Loosely mounted upon the shaft 56 at theouter side of the frame side 20 is a hand wheel 57.

\ A bevel pinion 58 is fixed with relation to the hand wheel 57, beingloose on the shaft 56. Said pinion meshes with a bevel gear 59 fixed onthe lower end of a vertical shaft 60, which is the main actuating shaftof the dofling machine. The lower end of said shaft is mounted in thebearing bracket 53.

A cam 61 has a groove 62 therein in which a roller stud 63 fixed to thelever '41 is arranged to travel, whereby the dofier head and has fixeduponsaid lower end an arm 67 (Fig. 6) which is connected to theclutchsleeve 65 by means of a link 68, whereby when the staff is rotatedthe clutch-sleeve 65 will be moved into and out of driving engagementwith the pinion 58. .When said clutch sleeve is out of such engagement,the

main drive shaft 60 may be rotated by the hand wheel 57. The upper endof the controlling staff 66 has a handle 69 fixed thereon above thetable 22, said handle being held in proper position by a spring-pressedpin 70 (Fig. 10) mounted thereon'and arranged to engage the table 22.

An arm (see Fig. 5) fixed on the controlling shaft66 is connected by alink 76 to an arm.77 which is fixed on a pin' 78 mounted in the bracket31.

A dog 79 fixed on said pin, so as to be rigid with the arm 77 isarranged'to engage a suitable projection stationarily mounted on thespinning frame near one end thereof, so that when the doffing machinereaches- 'to move the toothed wheel (Fig. 2) fixed on the rear end of ahorizontal shaft 86, said wheel being arranged to interengage withnotches.

or' recesses in the lower edge of the guiderail 23. The shaft 86 ismounted in a bearing in the central .portion of a U-shape bracket 87which has its ends fixed to one of the sides 20 of the frame. On oneside of the toothed wheel 85 is mounted a series of roller studs 88which are arranged to enter the groove in a cam 89 which is fixed on themain actuating shaft 60. The contour of said cam is illustrated inFigs.- 13 and 14:. Thecam groove is open at opposite ends and said endslie indifferent horizontal planes, the groove having an inclined portionbetween said ends. As the actuat ing shaft 60 is rotated, the cam 89will suci cessively engage the roller studs 88 on the wheel 85 and thusrotate the wheel step by step.

Upon the forward end of the shaft 86 is fixed a bevel gear 90 (Fig. 2)which meshes with a bevel pinion 91 fixed; on the lower end of thevertical shaft 92, which shaft is mounted in the bracket 87 and in thetable 22. On the upper end of the latter shaft is fixed a bevel gear 93which meshes with a bevel pinion 94 fixed on a short horizontal shaftwhichv is mounted in a bearing 95 upon the lower side of the table 22.The opposite end of the last mentioned shaft has a bevel gear 96 fixedthereon. which gear- I "meshes witha bevel gear 97 which isrotatablysupported beneath the table 22. The dofi'er bar37 extendsslidably but non-r0-' tatably through said gear 97. The step by steprotation of the driving wheel 85 causes intermittent" rotation ofthedofier bar 37 doifer head periodically through one hundred eightydegrees. When a full bobbin is lifted off from its spindle ,by means ofthe dofler head, the thread running from the bobbin to the spindle issevered by cutting mechanism (see Figs. 1, 3, 8 and 10) which may besubstan- -tially similar to the cutting mechanism shown in ourapplications above alluded to. Said mechanism comprises a guideway 101fixed on the upper side of the table 22, a slide bar 102 horizontallymovable in said ideway, and cutting means. carried by said slide bar andactuated by a stationary pin 103 which engages an arm 104.- on a rockshaft l05 mounted on' said bar, said rock shaft actuating the movablecutting device. The slide bar has 9. lug 106 thereon which is connectedbya link 107. with a free end of a horizontally swinging arm 108 whichis fixed on the upper end of a vertical shaft 109. A lever 110, bestshown in Figs. 9, 11

and 12, is fixed on this shaft near its lower end, and said lever has atension spring 111 connected thereto and to a bracket on the framework,whereby the shaft and arm tend to swing in-thel direction to move thecutter: slideforward ly and cause-the cuttin .Jneans to severthe threadrunning from t e. bobbin to the spindle. Anarm112 of the lever110'caa'ries a roller 113 which iszheld against one face ofa cam.member-114 which is'fixed UPOIlzthG main actuating'slmft 60. Ana-rm 115of'th'elever-110 is-connected by means of a link-116" to anarm. 117which is loosely 10 mountcd up'onthecontrollingstafi 66; An-

position to be-engaged by thelug121. In

the rotation of the cam member 114 the roller on -the arm 112follows-the contour of its cam, so as to permit the spring 111 to swingth'e'arm -108 to slide the cutting device at the proper moment. Incase abobbin is not removed from its spindle, the bobbin will be in positiontoobstructthe movement of the: cutting device, so that unless means wereprovided to prevent it, breakage of some of the parts might occur as thedofling machine advances. As will beseen, with the constructionjust-described, if the movement ofthe cutter slide is obstructed byfailure of the dofler head to remove a bobbin or in any other way, theshaft 109 will be affected and this will prevent the arm 117 fromwithdrawing the pawl 118 outof position to be engaged by the lug 121.Therefore said lug 121 will engage the pawl in the rotation of the cammember 114 and will rotate the arm 118 and the staff 66'to throw out theclutch 65'and thus disconnect the actuating mechanism from the drivinmotor 50.

A vertical rock-shaft 125 has fixed thereon a bell-crank lever 126-,(Figs; 2, 7 and 9) one armof which carries-a roller traveling in agroove 127 in the upper face of the cam member 114, the other arm beingconnected by a link 128 to a bell-crank lever 129 which projects upthrough anopenin in the table 22 and opens and closes the do or head. Onthe upper end of the shaft: 125: is fixedan arm 130 which is connectedby a link 131 to an arm 132 fixed on the lower-end of a rockshaft 133(Figs. 1, 7, 8 and 10) which actuates the mechanism for controllin thedescent of the bobbin in thedonmng tube. The contour of the cam groove127 is such as to impart the proper rocking movement to the; shaft 125.

A. vertical standard 150 (Figs;- 1 and 3) has its lower end seated in abracket 151 seis-mounted the upper end of the donning tube 153-which-guides the empty bobbins onto the spindles. A bracket' 154,mounted onthestandard'150, assists in supportingthe donning tube.-

After the empty bobbins have been .deposited' omthe spindles they arepressed down or seated on. the spindles. This. seating means-isgenerallysimilar to that shown in our priorapplications above mentioned,and comprises a slide 155 mounted to reciprocate ona vertical guide bar156 having its ends attached'to the bracket 151 andla bracket 157 thestandard 150.- The slide 155 is arranged-tube reci-procated by means .ofa link158attached thereto, the'lower end of saidtlink being connected tooneendof a lever159;which-.is pi oted between its :ends on: the slide 40for the dofi'er head. (See Fig.- 2.) The other end of saidzlever isattachednby-means-of a link 160 to the oscillatoryarm or lever 41 whichreciprocates the dofi'er head. A second slide161 is horizontallyreciprocable in the slide 155 and is arranged to bei slid by a verticalrod 162 passing loosely through an opening in the slide 161 and havingitsends fixed in a pair of arms 163 which are fixed on the rockshaft133. A bobbin-seating plate 164 is carried'by a rod 165 which is mountedfor vertical movement in the horizontal slide 161, said rod beingnormally pressed downwardly by a coiled spring 166 surrounding it.l/Vhen the vertical slide 155 is at the upper end of its movement, theshaft 133 is rocked to move the bobbin seater 164 into the donnin tube153 through an opening 167 therein. s the slide 155 is moved downwardly,said bobbin seater travels in a slot in the donning tube and iswithdrawn by movement ofthe arms 163 when the slide reaches the lowerend of itsmovement, the bobbin scater. traveling on the outside of thedonning tube during the upward movement of the slide 155. The length oftravel of the bobbin-seating device is greater than that of the dottingmeans. The lever 159 and link 160 are so mounted and connected that inthe reciprocation of the: slide 40, the end of the lever 159 to whichthe link 158 isattached will move through a greater vertical distancethan said slide 40.

A stop 168 is slidably mounted in a bearing 169 on the donnin tube 153for move ment into. and out of t e tube, (see Figs. 1, 3, 15 and 16) theouter end of said stop being connected by a link 170 to a lever 171which is pivoted between its ends on the bracket'157. An arm 172 isfixed on the upper end of the rock-shaft 133 and is notched to receive apin 173 which is fixed in the lever 171 upon the opposite side of itspivot from the link 17 0. When the rock-shaft 133 is swung to move thebobbin seater 164 into the donning tube, the stop 168 is simultaneouslywithdrawn from said tube. At the lower end of the donning tube 153 are asuitable number of spring fingers 174 extending into the tube andarranged to support a. bobbin and to yield to permit the bob bin to beforced past them.

The magazine 180 for empty bobbins (see Figs. 1, 3, 17, 18 and 19)comprises a member having a plurality of spaced vertical openings 181therethrough each adapted to receive a single bobbin in an uprightposition. Said member may be substantially the same length as thespinning frame. The magazine is supported by a series of brackets 182which are fixed upon the spinning frame and are connected with brackets183 fixed on the magazine by means of pairs of parallel links 184-. Themagazine is thus held at all times in upright position. Stop plates 185are fixed to certain of the links 184, (see Fig. 3) said plates havingnotches 186 therein to receive a rod 187 on the spinning frame, wherebythe magazine will be supported in its lowermost or operative po-.

sition. The lower ends of the bobbin recesses 181 in the magazine arenormally closed, or partially so, to prevent the escape of bobbins fromthe magazine, by means of a series of plates 188 pivoted on the underside of the member 180. In the forward ends of each of said plates isfi'Xed a pin 189, the upper end of which is connected by a coiled spring190 to a stationary pin 191 in the magazine, whereby the plate 188 isnormally held in its closing position. A pin 192 extending'through anarcuate slot 193 in the plate 188 and fixed in the lower faceof themagazine determines the limit of swinging movement of the plate. A cammember 194 fixed upon the top bracket 152 of the dofling machine isarranged to move successively into engagement with the lower ends of thepins 189 as the dotting machine travels along, so as to swing the plates188 to permit the descent of the bobbins successively from the magazineinto the donning tube 153.

In use, the machine is lifted into engagement with the guide rail 23 andthe bolster rail, and the mechanism is adjusted byrotating the-handwheel 57 to position the doifer head at the upper end of its movementready to descend upon the full bobbin beneath it. The bearings for theupper supporting rollers 24 are then rotated by the handle 28 to raisethe'framework and carry the toothed driving wheel 85 into engagementwith the guide rail 23. The clutch is now shifted to connect the motorwith the operating mechanism.

In the operation of the machine, the dofi'cr head35 is caused to descendand grip a full bobbin on one of the spindles, the bobbin seater 164being simultaneously moved downwardly in the donning tube to engage theupper end of a previously deposited empty bobbin and press it down onits spindle. The dofi'er head is then moved upwardly carrying with itthe full bobbin which it has engaged, and the bobbin seater is at thesame time moved upwardly on the I I 180 degrees, by the meanshereinbefore described, so as to bring the opposite gripping jaw inposition to descend over the succeeding bobbin. When the doffer head isat its lower limit of movement, the bellcrank lever 129 is swung toclose one gripping jaw about the full bobbin which it surrounds an toopen the opposite jaw so as to release the previously removed fullbobbin still retained therein. This released bobbin descends through asuitable chute 195 (Fig. 2) into a receptacle not shown in the drawings.

In each advancing movement of the machine the cam 194 at the upper endthereof will engage and swing aside one of the plates 188 on themagazine to permit the bobbin supported thereby to descend into thedonning tube 153. The descent of this bobbin will be arrested by thestop 168 which at this time projects into the donning tube. \Vhen thebobbin seater is moved horizontally into the donning tube, the stop 168is withdrawn, and the bobbin supported thereon will descend onto thebobbin seater 164 and will travel downwardly therewith until arrested bythe spring fingers 174 at the" lower end of the tube. When the bobbinseater has seated the previously deposited bobbin, it is movedhorizontally out of the donning tube and upwardly at the outside of saidtube and finally horizontally into the I tube above the bobbin held bythe spring fingers 174, the latter bobbin being forced past said fingersand onto the spindle by the bobbin seater in its next descent. The lever159 and links 158 and 160- give the donning bobbin seating means alonger vertical reciprocation than is imparted to the dofier head. Whenthe bobbin seater engages a anytime by operating the handle 69, and itwill be automatically stopped when it reaches the end of the spinningframe or in case the cutter device engages an-improperly seated bobbin.

We recognize the fact that various modifications in structure may bemade without departing from the spirit and scope of our invention, andtherefore we do not limit I ourselves to the exact construction hereindisclosed.
